CARBURETER.

SPECIFICATION forming part of Letters Patent No. 226,581, dated April13, 1880.

Application filed August 25, 1879.l

To all whom t may concern:

Be it known that I, MILES S. WRIGHT, of Brooklyn, in the county of Kingsand State of New York, have invented certain new and useful Improvementsin Oarbureters, of which the following is a description, reference beinghad to the accompanying drawings, forming part of this specification.

This invention relates to apparatus for carbureting air and gas forilluminatingpurposes, but is more particularly intended for carbu retingair, and will here be described accordingly.

`The invention consists in combining with a case having an extendedgasoline holding base a reticulated drum and a rotary pump mounted onhorizontal shafts, both journaled in or about the same plane, as willmore fully hereinafter appear.

The invention further consists of a novel combination of parts wherebythe air from the pump is restrained from being blown by the drum withoutpassing` through it, as will be more fully hereinafter set forth.

Figure l represents a side elevation of a carbureting` apparatusconstructed in accordance with my invention; Fig. 2, a central verticallongitudinal section of the same; and Fig. 3, a horizontal sectionthereof, mainly through the center of the perforated or reticulatedcarburetingdrum.

A is a rotary pump for forcing the air to be carbureted through thecarbureting wheel or drum. This pump, which may be of an ordinary or anysuitable construction, works on a horizontal axis, and is provided withany proper inlet and outlet, the pipe b here indicating the outlet forthe air to the carbureting wheel or drum. Said pump is situated at ornear one end of the apparatus, and is supported by the same main frameor case, B, which carries the carbureting wheel or drum and forms thechamber or receptacle for the gasoline.

O is the carbureting wheel or drum, which is situated near the oppositeend of the case B to that occupied by the pump. This drum is a verticalonethat is, rotates about a horizontal aXis-andis constructed withperforated or reticulated sides for the passage of the air forced by thepump through it, the pipe b delivering the air from the pump into thecase B on one side of the drum C ata point or level a little above theaxis of the drum.

The pump maybe operated as usual by a falling weight and gears, and thesame power be used to rotate the drum by belt from the pump -drivingmechanism as shown in the drawings. Said vertical perforated orreticulated drum O is lled with sponge, sawdust, or other absorbentmaterial, S, and works freely within the ease B, the lower portion ofwhich latter upto or about thelevel of the axis of the drum forms achamber for the gasoline or carbu retin g liquid, so that the drum isimmersed to` abouthalf its depth in thelatter when the chambercontaining the gasoline is fully charged. Thus the air to be carburetedis introduced by the pipe I), immediately above the surface of thegasoline on one side of the case B, and is delivered in a carburetedcondition after its passage through the perforated drum C by a pipe, d,on the other side of said case in like, or ap proximately-like,relationwith the surface ofthe gasoline-that is, immediately above thelatterwhen the case is fully charged. This is important to the perfectcarbureting of the air, and the vertical construction of the drum Greadily provides for it and exposes a large area of reticulated surfacefor the passage of the air through the absorbent material in the drum,and also insures the submersion iu the gasoline of acorrespondingly-large area of such drum-surface and amount of absorbentmaterial with which the drum is illed.

By such arrangement of the pipe attachments relatively to the surface ofthe gasoline and use of the vertical carbureting-drum not only is alarge percolatiug surface obtained, as above described, but, inasmuch asthe vapor from the gasoline which is lifted by the drum condenses andfalls during the rotation of the drum, the air entering the ease is morethoroughly and perfectly brought in contact with the rich gasoline assaid air percolates through the drum and its absorbent filling. Theconsequence of this is that a good illuminating effect for thecarbureted air may be obtained till the bulk of the gasoline in thechamber or case is consumed.

IOO

The shaft of the carbureting-drinn need only project through one side ofthe case, and consequently need have but a single stuffing-box. rlheupper portion of the case B, which covers the drum, may conform in shapeto the latter and leave but a contracted space between it and the drumbut otherwise itis desirable to have the case, or, rather, its baseportion, which contains the gasoline, of extended dimensionshorizontally, in order that the gasoline may be kept at atolerably-uniform level for a considerable period of time or protracteddraft upon said liquid, which is important for the proper operation ofthe carbureting-drum and ingress and egress ofthe air, as hereinbeforereferred to. Furthermore, the extension of the case B beneath the pump Anot only increases the capacity ofthe gasoline-chamber, Abut dispenseswith a separate support for the pump. Said case is also extended at itsother end beyond that portion of it which contains the drum, and suchextension is constructed to form a filling-odset, f, having afilling-nozzle, y, ou the same level (or thereabout) as that of thesurface of the liquid in the case when the latter is fully charged. rjhis enables the operator to ascertain when the wheel is properlyimmersed, and prevents all possibility of its too deep im nlersion. As,however, by the arrangement ofthe carbureting-drum G in theirregular-shaped caseB there would be a liability of the air blowingthrough the case without passing1 through the carbureting-drum, lprovide the lower portion of said case internally with guards or wings DD on opposite sides oi' the axis ol the drum and on both or reversesides of the latter, thereby forming partitions in the case in closeproximity to the sides of the drum, and more or less conforming to thecontour of the latter, so as to restrain the air from passing by thelower haltl of the drum without restricting the exposure of its sides.

I claiml. In combination with the case B, having an extendedgasoline-holding base, the reticulated drum C and rotary pump A, mountedon horizontal shafts, both journaled in or about the saine plane,whereby extensive holding capacity and extreme compactness are secured,substantially as set forth.

2. rlhe combination, with the case B, having an extended gasolineholdingbase, the reticulated carbureting-drum journaled on a horizontal axis,and the rotary pump A, journaled on or about the same plane with theaxis of the drum, ot the internal guards or wings, D D, on oppositesides of the axis of the drum and on both 0r reverse sides of thelatter, forming` partitions in the case B, substantially as and for thepurpose herein set forth.
